Problems solved by technology

[0004] For the ceramic tile grinding block used in the market, the grinding block is made of plastic (ie TPR) as the base material. Because of the poor temperature resistance of the plastic, it starts to dissolve when the temperature rises above 60 degrees, so it can only be used as the base material. Applied at a temperature of 60 degrees, the application range is extremely limited

Abstract

The invention discloses a silica gel base material, a silica gel tile abrading block and a preparation method of the silica gel tile abrading block. The silica gel tile abrading block is prepared by the following materials, by weight, 35% to 45% of methyl vinyl silicone rubber, 8% to 15 % of white carbon black, 5% to 10% of silicon powder, 0.3% to 1% of hydroxyl silicone oil, 0.05% to 0.1% of zine stearate, 40% to 50% of silicon carbide and 0.4 to 1% of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane. The raw materials of the silica gel tile abrading block are subjected to mixing, sulfuration and compression molding, and then an abrading block used for abrading tiles is achieved. The silica gel tile abrading block is good in high temperature resistance, high in elasticity, the service life of the abrading block is prolonged when the abrading block is used for abrading tiles, and the service life is prolonged by more than 3 times compared with a present plastic tile abrading block. At the same time, the silica gel tile abrading block can resist temperature lower than 200 DEG C, the scope of application of the tile abrading block can be greatly expanded. The preparation method of the silica gel tile abrading block is easy to operate, suitable for industrial production, and the tile abrading block prepared by the method is excellent in performance.

Description

technical field [0001] The invention relates to a ceramic tile grinding block, in particular to a ceramic tile grinding block made of silica gel and a preparation method thereof. Background technique [0002] The basic structural unit of organic silica gel is composed of silicon-oxygen chain links, and the side chains are connected with various other organic groups through silicon atoms. Therefore, the structure of silicone products contains both "organic groups" and "inorganic structures". This special composition and molecular structure makes it have the following excellent characteristics. Silicone products have high thermal stability, the chemical bonds of molecules will not be broken or decomposed under high temperature or radiation exposure, and the service life in the natural environment can reach several decades. Silicone products have good elastic properties. Silicones are among the most inactive compounds known. They are very resistant to biological aging, have ...
